IEEE 802.15.4 networkong stack covers PHY and MAC layers (PHY layer implemented in hardware and MAC optionally implemented in software). Also 6lowpan (IPv6 packet encapsulation) is implemented for use by IEEE 802.15.4 and BT LE networks.
Note: due to licensing restrictions (and despite project's name) we do not plan to implement any ZigBee related stack parts.
The PortKnocko project is composed of two parts: an iptables module (user space) and a netfilter module (kernel space). Both modules are used to implement the Port Knocking and SPA (Simple Packet Authentication).
This program shows the packets in a USB communication, by decoding the output of a command like "cat /sys/kernel/debug/usb/usbmon/0u" into more human-readable form
